I love audio books - well at least when I was commuting to school I did. I will still look forward to visiting the World eBook Fair from July 4th - August 4th to download my choice of free audio books! Maybe by then I will even have an iPod to play them on.
As for the Gutenberg Project - WOW! 1000s more reasons to sit in front of my computer! This is great for students when funding is close to, or nonexistent. I saw that Flatland was in the top 100 downloads - a book that I purchased last year for a math class. And several other books that have been on my reading list for years are listed. I could spend way too much time wandering on these sites!
